"he believes the eggs may be sticking to the webbed feed of visiting birds and transferred to nearby ponds." I then wonder how these "stuck" eggs get off the webbed feet of visiting birds. Carp and goldfish eggs are very adhesive. Once stuck to something the eggs are literally glued to the surface. They will not just drop off when the bird relands somewhere.
I vote NO. I need more proof than sticky eggs. Mosquito (Gambusia) fish do not lay eggs.
